Madonna’s voice is almost unrecognizable as she raises it half an octave to reach the aggressively cutesy “baby voice” that the song has come to be associated with today. Kitt’s vamping version was popular, but Madonna’s infantilized-Lolita take was the catalyst for the explosion of covers and parodies that followed, not to mention my kneejerk disdain.
I live in Canada and its well known. To be honest Madonna sounds very childish on the record but everyone kinda thinks it her song cause it gets played around Christmas a lot but maybe its because she is the queen of pop.
